The Zhukovsky Research Center has secured a patent for the design of a prospective supersonic passenger jet. This is confirmed by the invention’s description accompanying the patent, which TASS has reviewed.
Based on the patent documents, the aircraft is projected to cruise at a velocity of 2100 km/h (Mach 1.7). Furthermore, the anticipated loudness level of the sonic boom is estimated to be around 95 PLdB. The documentation also notes a reduction in noise during takeoff and landing phases when contrasted with conventional engines featuring axisymmetric nozzles and low bypass ratios.
The core objective of this novel endeavor, as emphasized in the description, is not merely to reintroduce supersonic travel, but to ensure its alignment with current standards for noise mitigation, range, and operational efficiency.
To attain the requisite performance benchmarks, the patent details a comprehensive set of engineering solutions. Notably, the aircraft will incorporate a swept wing, a distinctive fuselage configuration, and an engine nacelle housing a propulsion system comprising two engines with overwing air intakes and nozzles. Specific placements for the engines, nozzles, and aerodynamic components are described separately within the document, intended to contribute to noise reduction and enhanced flight performance.
Previously, the Zhukovsky Institute had indicated that Russian airlines are showing interest in potential future supersonic passenger aircraft. The institute estimates that the prospective fleet of such machines could eventually number in the dozens, with the primary demand originating from carriers serving current business and first-class passengers.
